PATENT GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 266,733, dated October 31, 1882.

Application filed April 12, 1876.

T 0 all whom it may concern:

Be it known that I, JOHN F. STEWARD, of Plano, Kendall county, State of Illinois, have invented new and useful Improvements in Grain-Binders for Harvesters, of which the following is a full description, reference being had to the accompanyingdrawings, in which-- Figure l is a side view; Fig. 2, a cross-section on line 00 :c of Fig. 1; Fig. 3, a detail of the binder-arm and twisting mechanism in position for operating; Fig. 4, a detail showing the inner face of the binder-arm; Fig. 5, a rear view of the binder-arm and head; Figs. 6, 7, and 8, details of the binding-wire guide.

This invention relates to certain improvements in automatic binding attachments for harvesting-machines.

Hy invention is embodied in the mechanism illustrated in the accompanying drawings, which I will now proceed to describe in detail, afterward specifically pointing out my improvements in the appended claims.

This device is designed to be used in a harvesting-machine of any ordinary or suitable construction, and therefore such machine is not shown.

The frame A may be a separate frame; or it may he a part of the regular frame-work of the machine with which the device is to be used.

The frame 13 is fitted into the frame A, and is supported upon the swinging arms 0 P, which arms are pivoted at each end, as shown at a. By this arrangement of the arms 0 P the strain does not come upon the pivots a, as the weight rests directly upon the arms P, which are supported upon the frame A. This gives the frame 13 a strong support and an easy forward or back movement, which brings the device into a position for binding either long or short grain in the proper place. For the purpose of shifting the frame into the position desired, it is connected by a lever or other suitable device with a' drivers seat; or the shifting may be placed under the control of an attend dant riding on the machine.

The frame 0 O is firmly attached to the frame B, and supports the bar or post E of the compressor, which is inclined inward, so as to bring the compressing devices partly over the grain which is being formed into gavels.

The wires or braces K K are bent into the form shown in Figs. 1 and 2, and are firmly attached to the post E and cross-bar C.

On the upper end of the post E is located a pulley or spool, L, upon which the compress ing-cord M is wound. The pivot of this spool L may be an extension ofthe wire K; or it may have a separate support, if desired. The spool L is provided with a fusee, N, upon which a short cord is wound, which connects the spool L with the upper end of the spring-bar J. This spring-bar J is coiled at one end to form the spring z. Its end projects out and forms the arm 2, as shown in Fig. 2, so that when the spring bar J is drawn down to its lowest point the arm a will be drawn up, so as to bring the treadle D to its highest point by means of the rod or link y.

The compressing-cord M, which is wound upon the spool L, is provided at its lower end with a knob, j, which in operation is caught under the catch it of the binder-arm H, and is held in that position while the arm H passes around the grain which is to form the gavel.

The operation of this part of the device is as follows: As the arm I'I rotates at its highest point the guide-spring 2' brings the knob) against the arm H and under the hook h, so that in its next round the cord M will be drawn from the spool L and passed around the gavel. In unwinding the cord M draws the cord of the spring J down upon the fusee N. The knob j is held in position until the projection h enters the depression of the cam wheel 70, when the catch or hook h releases the knobj a iid the spring-bar J winds the cord again on the spool L, which leaves the cord M ready to be caught by the next round of the arm H. The cord M is not released until after the twister has passed the curved bar I. This will complete the operation when the movement of the compression is continuous.

In order to impart an additional compression to the gavel when one of the notches a in the binder-arm His engaged with the catches 1] on the upright spring-arm \V, the attendant can draw down the binder-arm by pressing on the treadle D, the depression of the treadle through the medium of the spring-arm W, connected to said treadle, its catch a, and the notches u in the binder-arm serving to impart a further compression to the gavel. By carrying bands in the receiver S the gavel can be bound by hand, which is desirable in case of accident to the binding mechanism, or in case the supply of binding-wire becomes exhausted.

For automatic binding the arm H is provided with a twisting-hook, a, operated by the pinion b, which is attached thereto, as shown. The pinion b is provided with a dog or stop, 9, which prevents it from rotating and letting the wire off from the hook a while the arm H is passing around the gavel. The upper blade or-section, c, of the shears or cutter passes over the opening made for the hook at in the arm H, and is fastened firmly to the arm atits outer end. The moving arm or blade 01 of the cutter is pivoted to the side of the arm H, as shown in Figs. 2, 3, and 4, the pivot extending through the socket and projecting below, so as to form the arm f, by which it is operated. The blade cl is returned to its open position by the spring 6. The grain falls upon the platform or rack I, and, as the arm H passes around, the binding-wire t is drawn through the guide-plate 1a and carried around the gavel until the pinion b reaches the rack m, when the hook to commences to rotate and the other portion of the wire t is caught between the guide-wheels r and s, and the two wires are twisted together as the arm H advances with the pinion bin contact with the rack m. When the wires are twisted sufficiently the arm f comes in contact with the pin or projection n, and by means of the blades 0 d severs the wire, when the bound bundle is released and discharged from the machine. As the pinion 'b strikes the rack m' the dog or stop 9 is released from its contact with the pinion b by means of the rib 0 on the back of the curved plate I, so as not to interfere with the operation of the pinion I) and twistinghook a.

The binding-wire spool is locatedat any suitable position on the machine, so that the wire can pass through the tension device q, and from that to the guide-platep and between the guiderollers 1' r.

In order to bring the wire t within reach of the twisting-hook a, the lower end of the guideplate 19 is provided with a hook or curved section, 8, which will prevent the binding-wire from getting on the wrong side and bring it to the back or rear of wheel 8, so that the twisting-hook a, as it passes between the guidewheels 1" r and the wheel 8, will grasp the wire t and twist it. The cutter c d, when it severs the'binding-wire, leaves the end of it twisted around the hook at, so as to hold and bring it around thebundle at each successive operation.

In order to prevent the unbound grain from adhering to the bundle, the armH isprovided with a curved extension, H, which, as it passes through the rack or platform-I, detaches the grain which has not been grasped by thearm H, and holds it back until the twisting and re- I neath the platform or rack I a grain-box, B,

which is provided with sides 13, snfficiently high to hold the grain.

In addition to supporting an attendant the pins R R furnish a means which enables him to adjust the binding and compressing mechanism in the direction of the length of the grain by throwing his weight upon either of the pins, as desired. This will be accomplished by his act of adjusting himself to the best position for applying the band to the gavel, as

by so doing he will carry the binding and compressing devices to such a position that the arm H, cord M, and bars K will compress the gavel at or near its middle.

What I claim as new, and desire to secure by Letters Patent, is as follows:
